ELECTRIC HEATER AND STERILIZER.

Specication of Letters Patent.

Application led November 8, 1909. Serial No. 526,919.

My invention relates to 'improvements in l electricheaters and sterilizers. The obj ct of my invention is to provide adevice or heating and sterilizing fluid, such as waterLby 'means of electricity which requires a minimum current for such purpose, wlierein'elements are used which are non-destructible by electric action, in which when the device is removed from water no further'consumption of current occurs, and

which device can be handled at all times when. in use without injury to the hands,thef

said device being particularly advantageous for'sterilizing and precipitating -the foreign elements in the water.-

My improved device consists in the construction, arrangement and combination of parts shown in the accompanying drawings,

described in the following specification and pointed out in the appended claims.

Referring to the accompanying drawings which illustrate my invention, Figure l is a sectionalmview of my said device. Fig. 2 1s a side view of the same. Fig. 3 shows a sectional plan View and also a central longitudinal sectionalview of the carbon disks A and Bhereinafter described, and Fig. 4 re resents 4a sectional plan view of the porce ain ring C hereinafter mentioned and also a central longitudinal sectional view of the same.

In the. figures, A and B represent electrodes of o posite polarity fed by the rubber covere stranded wires and .51. Porcelain rings to hold the carbon disks in position are shown at C, and O indicates a porcelain frame containing said disk;l and rings.

F shows a groove on each side orclain frame O to allow s ace for screws E and small connecting bus ars D.

H indicates a groove filled with nonconducting insulating material to prevent parts D and E and wires 50 and 51 grounding on cylinder L, which cylinder is designed forl containing the parts therein shown.

p with the passage vof thev G Shows a small check valve screwed into the porcelain frame C, being in alinement Chambers between the disks A and B to allow electrical action on Water 'therein are shown at N. Perforations M are inlets and outlets for the passage of water into and from the cylinder L as acted on by the elements therein contained.

J is a handle preferably handling the device. v-

I shows a suitable tube in the handle for the wires 50 and 5l, the said tube being preferably soldered to cylinder L and flared at the top to hold the handle firmly in position.

Parts P represent small clips soldered to cylinder L to hold frame O imposition.

To operate the device shown in Fig. 1,' it is set in a vessel containing water, the same entering perforations M in the cylinder L and Ithence passing through top and bottom channels and the chambers N. Thenthe of wood 'for water is contained in the chambers electricalv action between elements A and B causes the water to heat insaid chambers, thereupon impelling it upward, and itl being'held in check from vdownward movement by check valve G. The warm water and steam thereupon rising, releases check valve G and allowscold water in the bottom of the cylinder L to ascendinto chambers N', repeating the said operation of heating, a circulation being effected by cold water rising from the bottom, the hot water being displaced.

' The device may be used on voltages varying from Q50 to 100 volts without changing the distances between electrodes. In said de vice,- platinum plated metal disks may. be

used instead of carbon disks, or any suitable conducting material that may stand 4the electrical action while Aplaced in thewater. Having thus described my inventionwhat I claim yas new and desire to secure by* Letters Patent is x l. In a device' ofthe character described the combination of a`vessel 'having top' and polarity havin bottom openingA alternately ment with sai centrally supported in saidl vessel, a plura ity of electrodes of opposite Patented Mar. ai, aan.'

spaced therein7 and current-conducting means leading:r through said handle and to said elements respectively.

2. ln a device of the character described the combination of a vessel having top and bottoni openings, a handle for said vessel having a longitudinal passage extending therethrough, a cup-shaped frame havinga bottom opening provided With a Valve centrally supported in said frame, a plurality of electrodes of opposite polarity having central openingsin alinement with said bottoni opening` alternately spaced therein, and current conducting means leading through said handle and to said elements respectively.

3. in a device of the character described the combination of a. vessel having topA and bottoni openings7 av recessed frame having a hottom opening provided with a valve centrally supported in said frame, a'pluralit-y of electrodes of opposite polarity having central openings in alinen'ient with said bottoni opening alternately spaced therein, and current-conducting means leading to said elements respectively.

ln testimony whereof l affix my signature. in presence oi two Witnesses.
